[200] Airplay server for C200 and A100

[daveyboy79]

Hi,

Not sure if i'm missing something. Photos work great, however sending video to the A110 does not seem to work. iPhone 3GS 4.2.1 (8C148a) indicates that it's sending video to the A110, however the A110 does nothing... Still shows main menu, no black screen or other indication of loading/buffering data.

Is there something else I need to do to get this working for me?

Cheers for letting this out in to the wild, it's because of people like you that we have such great tools. Much respect, thanks for this great piece...

Is the video from Itunes store? That won't play. Only videos you have synced yourself will play.

Try a different video file. Try rebooting (iPhone and A110).

If that fails get a log file and post it here. Telnet in and:

Code:

cd /share/Apps/Airplay-nmt/
killall airplay-a100
./airplay-a100-v > log

Hi ! First of all : thanks for this great work !!

I just installed your app on my A110 and it works perfectly both from iTunes PC/Mac and iPhone. I'm now able to stream video content from my portable devices ... ET CA C'EST ENORME

I was wondering if it could be possible to decline your app to act as an Airplay Speaker ?
I explain : we're now enabled to stream video content from iTunes which detect our popcorns as Video renderers, but we can't (or I just don't figure out how to) stream only-audio content...

Thanks again

See post #102.

Damn it :/

I looked for infos about Bonjour services used by Apple and found that their audio streaming is achieved through _raop._tcp.

Several apps have been developped to use original Airport Express or fake stations using these specs:

PHP Code:

Service Name:    YourMACaddress@yourSpeakerName
Service Type:    _raop._tcp.
Port Number:    5000

Text Record:<br>
txtvers=1001ch=2001cn=0,1001ek=1001et=0,1001sv=false001da=true001sr=44100001ss=16001pw=false001vn=65537001tp=TCP,UDP001vs=102.2001am=AirPort4,107001fv=75200.14001sf=0x4 


I tried to change the description of your service in daemon.sh :

PHP Code:

$BONJOURPATH/$BONJOURSERVER -n "$MY_MAC_ADR@$NMTVERSION" -t _raop._tcp. -p 5000 -x txtvers=1`echo -ne "\x1"`ch=2`echo -ne "\x1"`cn=0,1`echo -ne "\x1"`ek=1`echo -ne "\x1"`et=0,1`echo -ne "\x1"`sv=false`echo -ne "\x1"`da=true`echo -ne "\x1"`sr=44100`echo -ne "\x1"`ss=16`echo -ne "\x1"`pw=false`echo -ne "\x1"`vn=65537`echo -ne "\x1"`tp=TCP,UDP`echo -ne "\x1"`vs=102.2`echo -ne "\x1"`am=AirPort4,107`echo -ne "\x1"`fv=75200.14`echo -ne "\x1"`sf=0x4 -v 1 


and used Airfoil on my Mac :


The popcorn is well recognized as a remote speaker (model Airport).
And here is the debug window showing the app RTSP request :


The same company has released an audio receiver, Airfoil Speaker, which declares this service :

The virtual speaker isn't recognized by iTunes.

A small tweak on iPhone add a raop service to the device :

This one is usable through both iTunes and Airfoil.

Why couldn't we develop such tweak ?
Note : the encryption key used by iTunes and Airport Express has been cracked and released here

Hi

Just a thanks for the hard work in making this a reality.

I have installed the Airplay-NMT on my popcorn hour A110 and streamed a load of video content from my iPad through it from iTunes to movies and all worked great.

The only downfall was the lack of audio. I know reading through the thread that audio has not being incorporated and may never be (I hop not) but was wondering if anyone was working on it or had an alternative solution - like through another speaker or something as once the videos are streaming through the A110 all audio disappears even on the iPad?

Thanks again

I believe AirTunes encryption has been solved. But decryption hasn't. The two are not equivalent.

The reason Apple encrypts audio is to stop this being used as a mechanism to strip DRM from audio files sold through iTunes.

So they want to make it hard to pretend to be a sink for the data (e.g. AirTunes speaker).
They don't care about pretending to be a source for the data (e.g. iDevice).

All the software written that cracks AirTunes acts as a data source. I've seen nothing that acts as a sink. (One exception: cydia has an AirTunes speaker app for iDevices, but that is just an ARM binary pulled off an ATV2 and copied to iDevice).

I'm not quite sure what you are saying. Are you saying you get no audio whilst playing a video file?
Audio should be fine as part of a video file (e.g. mp4).
The audio not working being discussed is straight audio files (e.g. mp3).

I downloaded a free music video from iTunes and it played great over the NMT (very cool!). Maybe it played because it was free?

What I'd like to see is the exact opposite app. An app that will play from my C-200 over the internet or wifi to my iPhone. I don't want to transcode and store all these videos on my iPhone.

AirVideo is the standard for this. You will need to have a PC/Mac running which does real time transcoding.

Hi all, just installed AirPlay and it seems to play videos correctly. Only problem is I don't have sound with the video's. Any ideas how to solve this? (I have an A-110).

Thanks!

Can you copy the video to to a110 manually and see if it plays with audio?

Yes, I have that and it works OK. But I'd like to be able to watch these videos on the iPhone without the computer on - from what I understand, the C-200 uses much less power. I supposes I could use a Slingbox, but I bought the C-200 over the Slingbox assuming it could do more. Not being able to stream video over the internet is a real bummer.

Ahhh, thanks for the putting me straight. So the audio should be working then, unfortunately i am not getting any audio coming out from various video files (and they that all play on the popcorn hour normally) not even youtube videos have sound.

Any advice?

All my software does is negotiate a URL to play, then tells popcorn to play, say, "http://192.168.1.10:1234/filename.mp4"

There's nothing I do differently for audio and video.

When it's playing without audio, does volume (from popcorn remote) or mute have any effect. Does info button show an audio stream with a non-zero bitrate?

Hi, thanks for your reply! I tried AirPlay with the youtube native iPhone app. It played on my popcorn but without sound. I will try to test it as you suggest as well.
